The through macroperforations 16 can be crossed by braces 16a, which prevent the transverse deformations of the assembly by acting as tension elements in the deformations that occur as a consequence of the use.
El acoplamiento (véanse las figuras 1 y 2) se puede proporcionar mediante una capa perimétrica 17 de adhesivo, que se distribuye de modo que penetre, cuando los componentes están unidos, a través de las mallas de la red, y unen en una sola pieza la superficie de pisada 15 y la membrana 13. The coupling (see Figures 1 and 2) can be provided by a perimetric layer 17 of adhesive, which is distributed so that it penetrates, when the components are joined, through the meshes of the net, and joined in one piece the tread surface 15 and the membrane 13.
Como alternativa (véanse las figuras 3 y 4) se puede disponer, entre la capa de soporte 10 y la membrana 13, o entre la superficie de pisada 15 y la capa de soporte 10, una película 18 realizada en PVC o PU, y a continuación se puede realizar una soldadura a alta frecuencia entre la superficie de pisada 15 y la membrana 13 al fundir la película 18, dando lugar a que dicha película fundida penetre entre las mallas de la red con el fin de unir los componentes formando una sola pieza.

Haciendo referencia a la figura 5, en una forma de realización ligeramente diferente, se puede proporcionar una única macroparte 11 que afecta a toda la planta del pie sin partes 12, con independencia de la disposición de las macroperforaciones pasantes 16 de la superficie de pisada 15. Referring to Figure 5, in a slightly different embodiment, a single macro part 11 that affects the entire sole of the foot without parts 12 can be provided, irrespective of the arrangement of through macroperforations 16 of the tread surface 15 .
En este caso, la membrana 13 y su soporte 14 afectan asimismo a toda la planta del pie. In this case, the membrane 13 and its support 14 also affect the entire sole of the foot.
El adhesivo 17 o la película 18 están dispuestos en el perímetro. The adhesive 17 or the film 18 are arranged on the perimeter.
Haciendo referencia ahora a las figuras 6 a 9, una suela impermeable y respirable para el calzado según la invención que no forma parte de la invención, presenta una estructura que comprende una capa de soporte 110 realizada completamente en red, fieltro u otro material difusamente perforado, que como consecuencia constituye una única macroparte 111 grande. Referring now to Figures 6 to 9, a waterproof and breathable sole for footwear according to the invention that is not part of the invention, has a structure comprising a support layer 110 made entirely of net, felt or other diffusely perforated material , which as a consequence constitutes a single large macro part 111.
De nuevo, la suela comprende una membrana 113 de material impermeable al agua y permeable al vapor de agua (disponible en el comercio y realizado por ejemplo en politetrafluoroetileno expandido), que es laminada conjuntamente con una malla fina 114 destinada a soportarla, que se encuentra encima de dicha membrana, realizada en material sintético y que está prevista encima de la capa de soporte 110, que la cubre completamente. Again, the sole comprises a membrane 113 of water impermeable and water vapor permeable material (commercially available and made for example in expanded polytetrafluoroethylene), which is laminated together with a fine mesh 114 intended to support it, which is located above said membrane, made of synthetic material and which is provided above the support layer 110, which completely covers it.
La membrana 113 puede ser de material estanco o permeable al aire. The membrane 113 may be of airtight or air permeable material.
La membrana 113 está acoplada preferentemente mediante unos puntos de cola a la capa de soporte 110. The membrane 113 is preferably coupled by means of glue points to the support layer 110.
Se puede disponer una capa protectora 110a, por ejemplo de fieltro, debajo de la membrana 113, por ejemplo si la capa de soporte está realizada en red. A protective layer 110a, for example of felt, can be arranged under the membrane 113, for example if the support layer is made in a network.
Una superficie de pisada 115 de material plástico está montada sobre la capa de soporte 110 y está unida herméticamente a la membrana 113 por lo menos en la zona periférica de dicha membrana. A tread surface 115 of plastic material is mounted on the support layer 110 and is tightly bonded to the membrane 113 at least in the peripheral area of said membrane.
Se puede obtener el acoplamiento mediante la inyección directa de la superficie de pisada 115 sobre la capa de soporte 110 en un molde, con penetración por lo menos perimétrica a través de las mallas de la red o del fieltro, que presenta un espesor adecuadamente reducido en su perímetro, está perforado en el perímetro o está bordeado con red, con el fin de alcanzar la membrana 113. The coupling can be obtained by direct injection of the tread surface 115 onto the support layer 110 in a mold, with at least perimetric penetration through the net or felt meshes, which has a suitably reduced thickness in its perimeter, is perforated in the perimeter or is bordered with net, in order to reach the membrane 113.

5 115a, la superficie de contacto con el suelo. 5 115a, the ground contact surface.
El acoplamiento entre la superficie de pisada 115 y la capa de soporte 110 se puede obtener asimismo de la manera descrita en la primera forma de realización, es decir, por encolado o soldadura a alta frecuencia. The coupling between the tread surface 115 and the support layer 110 can also be obtained in the manner described in the first embodiment, that is, by gluing or welding at high frequency.
10 La suela puede estar acoplada a una pala 120, con el fin de proporcionar un calzado 121 que está montado sobre una plantilla de montaje 124 y acoplado en una zona descendente a una capa de relleno 122 de material expandido tal como EVA difusamente perforado, fibras de coco, etc. 10 The sole may be coupled to a shovel 120, in order to provide a shoe 121 that is mounted on a mounting template 124 and coupled in a descending area to a filler layer 122 of expanded material such as diffusely perforated EVA, fibers of coconut, etc.
La capa 122, cuando está realizada en EVA difusamente perforado o similar (por lo tanto impermeable de forma 15 inherente, pero que se hace permeable al aire), se puede utilizar como el medio para la soldadura a alta frecuencia, perimetral y hermética desde por encima de la membrana 113 hasta la pala 120. Layer 122, when made of diffusely perforated EVA or the like (therefore inherently impermeable, but made permeable to air), can be used as the means for high frequency, perimeter and hermetic welding from above the membrane 113 to the blade 120.
La aplicación de cola posteriormente en la superficie de pisada 115 no tiene que ser necesariamente hermética. The application of glue subsequently on the tread surface 115 does not necessarily have to be airtight.
20 El acoplamiento entre la suela y la pala 120 se realiza en la zona periférica de dicha suela de montaje y se proporciona, por ejemplo, por encolado o soldadura a alta frecuencia. The coupling between the sole and the blade 120 is carried out in the peripheral area of said mounting soleplate and is provided, for example, by gluing or welding at high frequency.
Una suela interior 119 de material respirable o difusamente perforado se puede disponer encima de la plantilla de montaje 124. An inner sole 119 of breathable or diffusely perforated material can be arranged on top of the mounting template 124.
25 La suela interior 119 se puede acoplar asimismo en una zona descendente a una capa amortiguadora 119a de polietileno o similar, difusamente perforado y con un contorno anatómico. 25 The inner sole 119 can also be coupled in a descending area to a damping layer 119a of polyethylene or the like, diffusely perforated and with an anatomical contour.
Asimismo, se pueden proporcionar otras capas, no representadas, tales como plantillas de limpieza, capas 30 absorbentes, etc. Likewise, other layers, not shown, such as cleaning templates, absorbent layers, etc., can be provided.
En la práctica se ha observado que se han alcanzado el propósito y los objetivos perseguidos de la presente invención. In practice it has been observed that the intended purpose and objectives of the present invention have been achieved.
